Epifanes Brush Thinner for Polyurethane Varnish 1 Litre

Get a smoother, more workable finish when brushing Epifanes polyurethane varnish. This brush-grade thinner is formulated specifically for Epifanes polyurethane topcoats, slowing the dry time just enough to let brush marks flow out before the film sets. The result is a cleaner, more professional finish especially in warm or dry conditions where unthinned varnish can drag and leave marks.

At 1 litre, this tin gives you enough thinner for multiple coats across a full season of brightwork maintenance. A small addition to your mix goes a long way toward improving application quality and reducing rework.

Best Use Case

Best used when brush-applying Epifanes polyurethane varnish in warm weather or low-humidity conditions where the varnish is drying too fast to level properly. Also useful for cleaning brushes and tools immediately after use. Not intended for spray application a separate spray-grade thinner is required for gun work.
